To all whom. t may concern.-

Be it known that I, JAMES E. HENRY, a citizen of the United States, and a resident of Sheboygan, in the county of Sheboygan and State of Wisconsin, have invented certain new and useful Improvements in Hoisting-Buckets; and I do hereby declare that the following is a full, clear, and exact description thereof.

Myinvention has for one object to provide for closing separable hoisting buckets by means of compressed air or other fluid under pressure; and a further object of the invention is to provide for automatic opening of said buckets, said invention consistin g in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.

Figure l of the drawings represents a sectional view of a separable hoisting-bucket provided with closing and openin g mechanism in accordance with my invention; Fig. A2, an elevation of what is shown in the first figure, the sections of the closed bucket being broken; and Fig. 3, a partly-sectional view indicated by lines 3 3 in the second figure.

Referring by letter to the drawings, A indicates each of a pair of sections constituting a separable hoisting-bucket. Each bucketsection is provided with inner upper corner side ears b, andthe ears of one section are in pivotal connection with the ears of the other section. Shouldered studs c, extending inward from the ear corners of the bucket-sections, have their reduced ends engaged with slots d in arms e of a cross-head B on the outer end of a rod C, rigid with a piston D in a vertical cylinder E, connected by links F to the upper outer corners of said bucket-sections. As a matter of detail the upper cylinder-head is shown provided with hollowr central crosslugs f, and a pivot-pin g, extending through the lugs, engages eyes in the upper ends of the links F, the lower ends of these links being also in pivotal connection with the bucketsections.

Engaging the pivot-pin g, between the cylinder-head lugs, I show a hanger G for connection with a hoisting-cable; but the details of construction latterly specified are susceptible of variation in practice without change of result-as, for instance, itwould be practical to provide the upper cylinder-head with lateral pivot-studs for the aforesaid links and a central ring-bolt for the hoisting-cable.

Pivotally secured in apertures h of the crosshead B are latches H, and leaf-springs I, made fast on said cross-head, oppose the latches. When the piston D is run up in cylinder E to bring the bucket-sections together, the springopposed latches snap on the lower cylinderhead, and thus the bucket is held closed, as best shown in Fig. 3. When the latches are caught on the lower cylinder-head, their beveled heads are in the way of a Spanner J, having an upwardly-extending lever-shank J in pivotal connection With ears t', extending laterally from the aforesaid cylinder, the construction and arrangement of the Spanner being such that its downward tilt will operate to displace said latches and permit automatic opening of the bucket. In practice it is designed that a striker K (indicated in Fig. .1) shall be arranged in the path of the Spannershank and that contact of these parts will result in automatic release of said latches.

In connection with the lower cylinder-head I show a tubular elbow-tting L, having a centrally-apertured packing-disk j held in its upper free end, and designed for insertion in the packing-disk is the tapered nozzle 7.: of a conveyer M for compressed air or other uid under pressure. By admission of fluid under pressure in cylinder E under piston D the latter is elevated to eect a closing of the bucket, as will be readily apparent by especial reference to Fig. l.

In practice the open bucket is lowered into a mass of material to be elevated and an attendant positions the nozzle of conveyer M inthe packing-disk of fitting L to inject fluid under pressure into cylinder E for the purpose of closing said bucket and causing engagement of its spring-latches with the lower cylinder-head, after which said nozzle is withdrawn and the hoisting operation takes place, the opening of the aforesaid bucket being subsequently effected by release of said latches incidental to tilt of spanner J in the proper direction automatically or otherwise.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A separable hoisting-bucket having its sections in pivotal union, a cross-head with which the bucket-sections have slide connection, a cylinder in link connection with said bucket-sections and provided with an inlet designed to have tight temporary connection with a nozzle of a conveyer for fluid under pressure, a piston in the cylinder opposed to inflow of said fluid, a rod connecting the crosshead and piston, latches in connection with said cross-head automatically en gageable with said cylinder, and means for retractirngT the latches.

2. A separable hoisting-bucket having its sections lin pivotal union, a cross-head with which the bucket-sections have slide connection, a cylinder in link connection with said bucket-sections and provided with a tubular fitting containing an apertured packing-disk for the temporary engagement of the nozzle of a con veyer for Huid under pressure, a piston in the cylinder opposed to inflow of said fluid, a rod connecting the cross-head and piston, latches in connection with said crosshead automatically engageable with said cylinder, and means for retracting the latches.

A separable hoisting-bucket having its sections in pivotal union, a cross-head with which the bucket-sections have slide connection, a cylinder in link connection with said bucket-sections and provided with an inlet designed to have tight temporary connection with a nozzle of a conveyer for fluid under pressure, a piston in the cylinder opposed to inflow of said fluid, a rod connecting `the cross-head and piston, latches in connection with the cross-head automatically en gageable with said cylinder, and a latch retracting spanner in pivotal connection with the aforesaid cylinder.

4. A separable hoisting-bucket having its sections in pivotal union, a cross-head having slotted arms engaged by studs on the bucketsections, a cylinder in link connection with said bucket-sections and provided with an inlet designed to have tight temporary connection with a nozzle of a conveyer for fluid under pressure, a piston in the cylinder opposed to inflow of said Huid, a rod connecting the cross-head and piston, latches in connection with said cross-head automatically engageable with said cylinder, and means for retracting the latches.

5. Aseparablehoisting-bucket, and means in conjunction therewith for the utilization of fluid under pressure asaclosingmedium,latch mechanism for holdin g the bucket closed, and latch-retractive mechanism.

In testimony that I claim the foregoing I JAMES E. HENRY.
